<p>A loudspeaker protection system comprises filter means for defining one or more frequency bands of an audio signal, controllable amplifier/attenuator means coupled to the filter means, and processing means coupled to control the amplifier/attenuator means, such as to determine audio power in at least one of said frequency bands representing relevant loudspeaker protection information used for selective audio power control in said at least one frequency band. This system has the features for a fast and/or slow thermal protection, as well as for a cone excursion protection all for a loudspeaker in such a system.</p> |
